PIANO.

SPECIFICATION forming part of Letters Patent No. 326,105, datedSeptember 15, 1885.

Application filed June 8, 1885,

To all whom it may concern/.-

Be it known that I, GEORGE 0001:, of Boston, in the county of Suffolk,of the Commonwealth of Massachusetts, have invented a new and usefulImprovementin Piano-Fortes; and I do hereby declare the same to bedescribed in the following specification and represented in theaccompanying drawings, of which Figure 1 is a front elevation, and Fig.2 a transverse section, of the key-holding part of a piano-forte frameor case and its movable shelf and compound key-fall or cover inaccordance with my invention, the nature of which is defined in theclaim hereinafter presented, the key-fall or cover being in such figuresrepresented as fully open or turned back to its extreme position, inwhich instance the front section projects over and rests flatwise uponthe shelf and the rear section or name-board is in a vertical position.Fig. 3 is a transverse section of such parts, showing the key-fall orcover as closed over the keys or in its forward position. Fig. 4 is avertical and longitudinal section of the shelf and its supporting endportions of the pianocase.

In such drawings, Adenotes that part of an upright-piano case in whichthekeys are usually situated, it being provided with a shelf, a,arranged above the keys and name-board and extending from the latter.Such nameboard (shown at b) constitutes the rear section of the compoundkey-fall or cover B. This name-board at its rear part is so hinged tothe case or frame as to be capable of being turned from a horizontalupward into a vertical position, or vice versa. When. back or in itsvertical position, the name-board rests against or covers the front edgeof the shelf a. \Vhen the name-board is turned down into a horizontalposition, it extends upward at its rear part to the under side of theshelf, and between a lip, Z, projecting down from the shelf at its frontedge and another such lip or projection, m, also extending down from theshelf at a short distance in rear of thelip Z.

The shelf is adapted to the frame so as to be capable of slidinghorizontally and laterally therein. It thus becomes not a stationaryshelf, as ordinarily used, but a movable (No model.)

one. To this end the shelf has grooves k in its ends to receive tonguesm, extending from the end parts, a, of the ease. The shelf also rests atits ends on ledges 0 0, projecting from such end parts a.

\Vhile the name-board is being turned back ward it will move or slidethe shelf rearward until the nameboard passes out of the space betweenthe two lips Z and m. So while the nameboard is being turned forward, assoon as it may enter the said space and butt against the front lip, Z,it will commence to advance the shelf, which will be slid forward duringthe rest of the downward movement of the nameboard.

The front section of the key-fall or cover is represented at c, itbeingso hinged to the rear section or name-board (which, as shown, is concaveon its upper surface) as to be capable of being turned upward into avertical position relatively thereto when such nameboard is in itslowest position. \Vhen the two sections are thrown entirely back, thatmarked 0 extends over and rests upon the shelf. The hinges connectingthe two sections are represented at p.

The front section, 0, of the key-fall 'or cover has a lip, 0', extendingfrom it at a right angle to it at its front end, such lip, when thecover is closed, resting on that part, 8, of the case which is directlyin front of the keys i, all being as shown in Fig. 8.

By having, with the compound key-fall, the shelf movable, as described,by the nameboard or rear section of such key-fall, a wider shelf can beused than would be the case were the shelf stationary, it beingunderstood that in such instance the front section of the key fall,whenin its rearmost position, is over and upon the shelf.

I do not herein claim a key-fall or cover made in two sections soapplied or hinged together and arranged with a stationary shelf thatwhen such cover or key-fa11 is turned back to its rearmost position thefront section shall be wholly in rear of the back section of it andunderneath the shelf, all being as shown in the United States Patent No.183,773; nor do Iherein claim, broadly, the key-fall constructed in twosections hinged to each other and arranged so that when turned whollyback the rear section shall be in an upright position and bear againstthe front edge of a stationary or immovable shelf, and the front sectionshall extend over and cover or rest upon such shelf, such being thesub-.

and having the rear section or name-board provided with an extension toproject between the said lips and serve with them to effect lateralmovements of the shelf during the movements of the key-fal], asexplained, the front section, when entirely back, extending over suchshelf, all being substantially as rep- 0 resented.

GEORGE COOK.
